摘要:

运用有限元软件对指纹锁壳体零件的成形过程进行模拟分析,获得了合理的工艺方案,并设计了一套基于伺服机械手送料的多工位传递模。并针对侧面收口成形后制件筒口边缘部位形成倒扣特征造成的放料、定位和取件困难的问题,在侧面收口、侧面整形、侧冲孔和切口工位将工作零件设计为活动式模组结构,运用模内、模外多套导向系统对上下模及模内运动部件作导向。经试模生产,模具工作可靠、制件表面质量及尺寸精度符合技术要求,生产效率较原单工序模具有较大提高,可为同类产品的工艺方案优化及模具结构设计提供参考。

The forming process of fingerprint lock shell part was simulated and analyzed using finite element software, the reasonable process scheme was obtained, and a set of multi-station transfer die based on servo mechanical hand feeding was designed. Then, in view of the difficulties in material feeding, positioning and taking out caused by the inverted characteristics at the edge part of barrel mouth after side closure forming, the working parts were designed into a movable module structure at the side closure, side shaping, side punching and cutting stations, and the multiple sets of guiding systems outside and inside the die were used to guide the movement components of the upper and lower dies and inside the die. After trial production, the results show that the die work is reliable, the surface quality and dimensional accuracy of the parts meet the technical requirements, and the production efficiency is significantly improved compared with the original single-process die. Thus, it can provide reference for the process scheme optimization and the die structure design of similar products.
